But since you do not tell the Brand and model of the Processor it's hard to tell.
The Decklink IP 100G is a Full ST2110 card. An IP video protocol that is just rissing.
Altho a LOT of users report that the BMD ST2110 is difficult compatible with any other brand and a lot of compatibility issues arrise.
I would rather go for a more conventional approach by using Fiber converters to convert the Videocard direct to Fiber. ( 3 ports of 4K ) Also keep in mind that you need a video card that has sync across the 3 outputs.. Otherwise you will notice tearing artifacts on your ledwall.
